LAS VEGAS -- NewPort Communications Inc. today announced a serial 10-gigabits-per-second CMOS transceiver chip set that it said enables OC-192 Sonet/SDH communications with power consumption of just of 1.5 watts from a 1.8-volt supply.
The chip set, unveiled at Networld+Interop here, includes the NP1010, a 10-Gbit/sec. 16:1 multiplexer with clock multiplication unit; and the NP1011, a 10-Gbit/sec. 1:16 demultiplexer with clock and data recovery. Drawing on the company's proprietary C3MOS technology, the two-chip solution consumes significantly less power than 10-Gbit/sec. devices fabricated in silicon germanium, gallium arsenide or bipolar processes, the Irvine, Calif.-based company said.
The NP1010 transmitter interface chip implements all necessary Sonet/SDH serialization and transmission functions and incorporates a FIFO for decoupling the internal and the external timing domains. The NP1011 receiver performs Sonet/SDH-compliant CDR and deserialization functions. The low-speed 622-megabits-per-second (OC-12) interface for each device is compliant with Optical Internetworking Forum-Physical Layer Group's OIF99.102 standard.
The transceiver solution is designed for use in equipment for bandwidth-intensive, fiber-based backbone networks that support the explosive Internet and e-commerce markets. Applications include ATM switch backbones, Sonet/SDH optical modules, OC-192/STM-64 transmission equipment, add/drop multiplexers, digital cross connect switches, Sonet/SDH test equipment, terabit routers, and other OC-192/STM-64 (9.9 gigabits per second) networking equipment.
"Conventional serial 10-Gbit/sec. solutions in the market today consume extraordinarily high power and require very expensive specialty processes," said Joseph Vithayathil, vice president, sales and marketing for NewPort Communications.
Using a mainstream CMOS production process, he said, allowed NewPort to integrate more functions on the chip, thus reducing the power consumption and permitting high-volume manufacturing. NewPort's own C3MOS design technology and proprietary cell libraries enabled the company to achieve maximum attainable speed while meeting the stringent jitter requirements of Internet applications, he added.
Working samples of the NP1010 transmitter, NP1011 receiver and an accompanying evaluation board have been shipped to NewPort Communications' system development partners. Samples for the general market will be available in September, with production scheduled for the fourth quarter. The NP1010 and NP1011 are each packaged in 15-sq.-mm 120-pin BGA packages.
